Linguistic annotation of natural language corpora is the backbone of
supervised methods for statistical natural language processing; further,
it is essential for evaluation of both rule-based and supervised systems
and can help formalize and study linguistic phenomena.

Multiword expressions (MWEs) are word combinations, such as all of a
sudden, hot dog, to pay a visitor to pull one's leg, which exhibit
lexical, syntactic, semantic, pragmatic and/or
statisticalidiosyncrasies. Computational research on MWEs encompasses
NLP modelling and processing as well as annotation.

Construction Grammar (CxG) is a linguistic framework of relevance to
both linguistic annotation and MWEs. In this framework, constructionsare
form-meaning pairings of varying degrees of internal complexity and
lexical fixedness, including idioms like the-Xer-the-Yer (the more the
merrier, etc.) and semantically productive meaning-bearing syntactic
patterns (e.g., the caused-motion construction: Mary pushed the napkin
off the table; the ditransitive construction: He gave her a burger),
which give rise to novel usages (e.g. Mary sneezed the napkin off the
table; He grilled her a burger). Annotation and automatic processing of
constructions pose significant challenges: because constructions are
form-meaning pairs that can be more or less fluid in form, determining
the annotation units for a construction is not straightforward. For the
above reasons, grammatical constructions were elected as a joint focus
of interest by both the MWE and the LAW communities to constitute a
special theme within a joint 2-day workshop.

We invite long and short papers focusing on research related to the
following topics (as well as others traditionally associated with
previous editions of the LAW and MWE workshops):

* Evaluation of MWE and construction annotation and processing
techniques

* Computationally-applicable theoretical studies on MWEs and
constructions in psycholinguistics, corpus linguistics and grammar
formalisms, and/or how such studies can impact annotation of constructions

There is no limit on the number of reference pages. Authors will be
granted an extra page for the final version of their papers. The Program
Committee will determine which papers are better suited for oral or
poster formats.

PARSEME Shared Task System papers will be concerned by specific
guidelines and a separate reviewing process.
